Recent advancements in quantum computing and the NIST standardization of quantum-resistant cryptography have motivated security-conscious organizations to assess the impact of the quantum threat across their digital ecosystems and explore innovative cyber-security solutions, including post-quantum authentication, to stay ahead of emerging threats.
In our latest article, we argue that no RFP should result in procuring an authentication system that is not quantum-safe in 2025.
Protection From Quantum and Classical Threats
Traditional cryptographic algorithms, such as RSA and Elliptic Curve Cryptography (ECC), rely on mathematical problems that are resistant to classical computers, but quantum computers can break using Shor’s algorithm.
In contrast, post-quantum authentication (PQA) is built on post-quantum cryptography that leverages more robust mathematical problems to resist both classical and quantum attacks. Therefore, organizations adopting PQA are not just preparing for a post-quantum future — they are also reinforcing security against classical threats.

Because post-quantum algorithms are designed with more robust foundations, they provide greater overall security — regardless of whether quantum computers become a widespread threat tomorrow or in a decade. This helps organizations eliminate current risks and future-proof their authentication systems.
Quantum Resistance as a Necessary Authentication RFP Requirement
Organizations considering a new authentication solution should recognize that legacy authentication based on classical cryptography is not a long-term option. Why is that?
- Regulatory alignment: Governments and standardization bodies (e.g., NIST, ETSI, and ENISA) are urging organizations to transition to post-quantum cryptography by 2030.
- Keeping trusted systems: Authentication providers that do not adopt quantum-resistant methods today risk delivering solutions that will soon be obsolete and will not provide a sufficient level of trust.
- Avoiding unnecessary migrations: Investing in a classical authentication system today means another costly and complicated migration in the near future. Opting for PQA early helps organizations avoid redundant implementation efforts.
In short, organizations should only select post-quantum-ready authentication solutions in their RFPs if they want a future-proof, cost-effective, and secure solution.
The Best Time to Switch Was Yesterday
Security leaders who want to avoid the impact of quantum threats recognize that choosing authentication based on classical cryptography is no longer an option. Only implementing post-quantum authentication in advance before Q-Day comes ensures protection against both current and future threats.
While some organizations view PQA as a defense against still distant quantum threats, leaders in cyber-security recognize it offers superior protection over classical authentication methods — regardless of whether quantum computers capable of breaking existing cryptography become practical in the near term. With PQA solutions like PowerAuth®, organizations can transition smoothly and avoid unnecessary security risks and additional costs.
